ELEVATED-RAILROAD CONSTRUCTION.

SPECIFICATION forming part of Letters Patent No. 263,088, dated August22, 1882.

1 Application filed March 25, 1882. (No model.)

To all whom itmay concern:

Be it known that I, NORMAN ALLEN, of Roekawav Beach, in the county ofQueens and State of New York, have invented certain new and usefulImprovements in Elevated-Railroad Construction, of which the followingis a full, clear, and exact description.

My invention relates to the uprights or posts which support thesuperstructure ofelevated railroads; and it consists in the peculiarconstruction and arrangement of parts, as hereinafter fully described.

Reference is to be had to the accompanying drawings, forming part ofthis specification, in which similar letters of reference indicatecorresponding parts in all the figures.

Figure 1 is a front elevation of one of my improved railroad-posts,showing the two parts secured together, and showing the method ofsetting the post in the'ground. .Fig. 2 is a detailed view of the lowerend of the upper part of the post, showing the slotted flanges forsecuring the same to the lower part. Fig. 3 is a detailed sectionalelevation of the upper end of the pedestal part of the post, taken onthe line a." m of Fig. 5. Fig. 4 is aeross'section taken on the line y yof Fig. 2, and Fig. 5 is a cross-section taken on the line 2 z of Fig.1.

A represents the upper part of the post, and B represents the base orpedestal part of. the post, which is made angular, or so as to form theside flanges a it below the surface of the ground; or this part of thepost maybe round and solid or tubular. The upper end of this pedestalpart of the post is formed with the sleeve G, which is formed with theslots 1) b and side flanges c c, which are formed with the perforationsd d, and the lower end of this part of the post is formed with the broadflange or base-plate D. Between the baseplate D and the sleeve (3, atabout equal distances therefrom, are formed the intermediate flanges, EE, as clearly shown in Fig. 1. The lower end of the upper part, A, ofthe'post is ofa size adapted to fit in the sleeve 0 of the pedestal partof the post, and is formed with the side flanges, ff, which are madewith the slots {1 g, which flanges and slots correspond with the flangesc c and perforations d d of the pedestal part of the post, so that whenthe pedestal part of the post is set in the ground the upper part, A,may be set in the sleeve 0 and secured to the part A by the heavy boltsit, which pass through the said perforations and slots in the saidflanges.

In setting the pedestal part B of the post I first set in the ground theconical walling F of felt, the lower end of which is provided with orrests upon the sheet G of felt. In the center of this conical walling offelt I place the pedestal or base portion B, and then fill the spacebetween the part B and wall of felt with broken stone and gravel andcover the top with a layer of any waterproof cement or coaltar, or both,and finally tamp down the earth around the walling F as firm and solidas possible. By this means it will be seen that the post is entirelysurrounded by a water-proof wall, so that no water can reach the post,which, when frozen, would tend to lift and heave the post out of theground. Besides, the conical form of the walling F, together with theflanges E E of the base of the post, causes the ballast of stone andgravel to effectually hold the post against all upward as well aslateral movement.

In order to elevate the upper part, A, of the post for leveling thetrack, it is only necessary to loosen the nuts of the bolts 1' i andapply a suitable lifting-power-such as a jack-screw or suitably-arrangedlever-t0 the said upper part and raise it to the required height, andplace under it, upon the table h of the pedestal part B, (shown in Fig.3,) a wedge or block of suitable thickness, and then tighten the nuts ofthe said bolts to place again.

It will be observed from Fig. 5 that the flanges c c are formed uponopposite sides of the slots 11 bin the sleeve 0, which arrangementserves to support the upper part of the post equally upon both sidesofthe post.

Though I have shown the walling F circular and conical in form, it willbe understood that I do not confine myself to such construction.

Having thus fully described my invention, I claim as new and desire tosecure by Letters Patent 1. The wallingF forsurrounding the ballast,

made conical and adapted to be used with the lower sheet, G,substantially as and for the purposes described.
